THRESHING-MACHINE.

Specification of Letters Patent.

Patented June 3, 1. 91 3.

Application filed February 19, 1912. Serial No. 678,574.

To all whom it may concern:

Be it known that ALBERT M. Sonnssnn, deceased, who was a citizen of the United States, residing at Prairie View, in the county of Phillips and State of Kansas, did invent certain new and useful Improvements in Threshing-rlachines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in threshing machines and more particularly to a grain separator, and my object is to provide a dev1ce of tlns character with improved means for thoroughly cleaning and separating the grain from all weeds and chaff.

A further object of the invention resides in providing a revolving drum into which the grain is deposited from the threshing cylinder, whereby the main separation of the grain from the weeds, etc, is accomplished.

Still another object of the lnvention resides in the provision of a plurality of sieves and fans adapted to act upon the grain after leaving the drum in order that the same may be thoroughly and positively cleaned of all extraneous matter.

A still further object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture, and one which is Very efficient and useful in operation.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out 1n the specification and claim.

In the accompanying drawings forming a part of this application, Figure 1 1s a s1de elevation of the machine complete. Flg. 2 is a longitudinal section therethrough. Fig. 3 is a transverse section therethrough as seen on line 3 3, Fig. 2.

In carrying out the invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a frame of any desired size, from the under face of which at the front and rear ends thereof, are extended the brace rods 2 which have mounted thereon, the front and rear axles 3 and 4, respectively, said axles carrying thereon, the wheels 5, whereby the frame and parts carried thereby may be readily moved from place to place. Mounted on the sides and ends of the frame '1, is a plurality of vertical bars or the like (3 which are braced by means of the rods 7, and rotatabl y mounted on the horizontal rods 8 which connect pairs of vertical rods on opposite sides of the frame, is a shaft 9 which carries thereon, the usual or any preferred form of threshing cylinder 10. Also carried between these lmrizontal bars 8 and disposed immediately below the cylinder 10, is the concave grate 11, and supported on a framework below the concave 11, is an endless elevator 12, the chains 13 of which extend over the sprockets 1 t. A shaft 15 extending transversely of the frame 1 and between the reaches of the endless elevator 12, is provided with a pair of sprockets 16, the teeth of which engage the chains 13 to rotate the elevator as said shaft is rotated. This shaft 15 may be rotatably mounted in any desired Il'lZlIlllGl' on the side bars of the frame 1, the same being provided with driving pulleys 17, whereby said shaft may be rotated from any source of power (not shown), and it will be seen that the grain that is passed through the grate 11 will fall upon the elevator 12 and be conducted to any desired means for further separating the grain from the chaff.

A drum or the like 18 formed of a pair of end bands 1!) and a plurality of spaced apart rods 20 is rotatably mounted in the frame 1 to the rear of the cylinder 10 by being mounted between a plurality of guiding pulleys 21, said pulleys being supported in position by any form of brackets desired. The one end band of the drum 1.8 nearer the cylinder 10 has the peripheral edgethereof provided with beveled gear teeth 22, and said shaft '15 which extends transversely of the frame 1 immediately forward of this end of the drum, is provided with a bevel gear 23 which meshes with the gear teeth 22, whereby when said shaft 15 is rotated, the drum 18 is adapted to be likewise rotated. Into this end of the drum which has the gear teeth thereon, extended the upper end of the elevator 12, whereby the contents thereof may be emptied within the drum as the same is revolved, while a fan 24 carried on a shaft 25 immediately below the elevator 12, is incloscd within a casing 26, the mouth of which leads toward the one end of the drum 18, whereby the separation of the grain from the chaff will be aided considerably as said drum is rotated, and carried within said drum, are the diagonal cross rods 27 which, as said drum is rotated, cause the contents thereof to drop to the lowermost portion of the same.

As the grain is separated from the chaff through the rotation of the drum 18, the same is dropped upon a movable flooring or the like 28 which is suspended from the main frame 1 by means of the hangers 29. The greater portion of this flooring is foraminous, as shown at 30, to form a substantial sieve, and a crank shaft 31 rotatably mounted on a framework 32 suspended below the flooring 28, is connected by means of an arm 33 to said flooring 28, whereby as said shaft is rotated, said flooring will be reciprocally agitated. A fan 3a is mounted on said shaft 31 and the draft resulting therefrom is directed toward the sievelike portion of the flooring 28, so that the chaff will be blown from the grain, and as the grain falls through the sieve-like portion 30, the same will fall into a grain shoe 35. This grain shoe has mounted therein, a sieve 36 and a screen 37, the latter being inclined at an angle with respect to the former so that the matter deposited thereon, may readily pass to a chute or the like 38. Tee complete grain shoe is connected by means of an arm 39 to an additional crank shaft 40, whereby as said shaft is rotated, the complete shoe will be reciprocally agitated to cause the grain on the sieve and the screen to pass through these respective members and the matter passing through the screen 37, will be deposited on the flooring of the grain shoe and passed to a chute tl, from which it may be conducted to any desired place in any desired manner, whatsoever,

while the matter remaining deposited on the sieve 36, may pass to a chute 1-2, from where it may be conducted in any desired manner back to the other elevator, if so desired, to be again passed through the process of elimination.

lVhile I have not so shown the same, a motor of any desired type may be mounted on the frame of the device which may have operative connection with the shaft 15 and the various other shafts carrying the fans and cylinder, but as this forms no particu larly essential part of the invention, it is not deemed necessary to consider the same f in detail.

From the foregoing description, it Will be seen that there is provided a simple, efficient and inexpensive means for accomplishing the objects of the invention, but whilethe elements herein shown and described are well adapted to serve the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

.Vhat I claim is 2- In a device of the class described, the combination with a frame; of a separating drum rotatably mounted therein and comprising a pair of end bands, said bands being angular in cross section, a plurality of spaced longitudinal rods secured to the horizontal faces of said end bands to form the wall of said drum, and a pair of crossed diagonal rods connected at their ends to the last mentioned faces of said end bands to brace the latter and also provide an agitating means for the contents of the drum, the

laterally extending faces of the angular bands affording a means for rotatably supporting the drum in the frame.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
